Hm... actually it performs a _bit_ better with the new world+kernel ;) make buildworld 18749.83 real 16143.33 user 1981.61 sys make buildworld 18758.40 real 16191.54 user 1999.10 sys make -j2 buildworld 19297.45 real 16570.93 user 2127.90 sys make -j2 buildworld <not yet finished> Next I'll try some CFLAGs... -- Oliver Lehmann http://www.pofo.de/ http://wishlist.ans-netz.de/
